There are plugins for almost everything you can imagine. Most are free and should come installed with your WordPress installation. These plugins include Jetpack, which provides various features, like sharing buttons and image galleries; WP to Twitter, which helps you post updates to Twitter without having to leave your WordPress site; and Akismet, the spam-fighting plugin that protects your posts against malicious commenters.
Plugins can make your website better or worse. You need to be able to tell whether they are worth the money you pay for them or not. You also want to be able to tell which ones are worth paying for and which ones are not. That’s where the third question comes in: is it worth it? That’s all that matters here. If you spend $50 on a plugin that helps your site run smoothly, it’s worth the money. If it doesn’t do anything for your website or causes issues, it’s not worth the money you spent. Read reviews first!
There are several ways to determine what a plugin is about and whether or not it does what you want it to do. You can research it online, review sites, or ask other users in your community about it via Twitter or email.
Ideally, you want to see if others have problems with the plugin and feel the same way you do. Perhaps there is a new feature you need that isn’t yet available in the plugin and could be added with a future release? If so, maybe this plugin isn’t for you after all. Plugin developers and testing groups such as the Plugin Ongkir Review Team work hard to ensure their plugins are working and considered stable, with any issues addressed. These developers are looking for problems in the code, which is readily available on WordPress.org and within each plugin’s settings. If there’s nothing but praise that others have to say about a plugin, then chances are other people aren’t having problems with it.
